Abstract

An electronic temperature control bistable water return for hot water circulation comprises a body, a middle partition sealing element, a hot water pipe inlet, a hot water pipe outlet, a cold water pipe inlet and a cold water pipe outlet, wherein the middle partition divides the inner space of the body into a hot water cavity and a cold water cavity; the sleeve with the vertical tail internal thread is sleeved at the thread outside the external thread transmission shaft, and the temperature sensor is embedded in the hot water cavity and outputs a temperature parameter signal to the central control unit; the middle partition 3, the sealing piece 5 and the sleeve with the vertical tail internal thread at the designated position form a valve mechanism together for blocking the connection of a channel between the hot water cavity and the cold water cavity; the channel is opened to form a water return device communicated with the cold and hot water pipeline.

Description

Electronic temperature control bistable water return device

Technical Field

A water return device starts a motor to drive a threaded piston to slide through an electronic temperature control signal so as to open and close a connecting channel between cold and hot water pipelines.

Background

All can have the demand of using hot water in domestic and public environment, nevertheless because the hot water source often can have a certain distance with the water end to cause to be detained the water after a large amount of coolings in the pipeline, simultaneously because ordinary water injection well choke does not have the backward flow function, thereby lead to producing a large amount of water of abandoning before using hot water. The washbasin is used for washing hands frequently, and is also an application link which causes the highest frequency of water abandonment, so that the problem of water abandonment of the washbasin is solved, and fresh water resources can be saved more effectively. The existing circulating device is provided with a special water return pipeline to form a circulating loop so as to circulate hot water, so that a user who does not have the special water return pipeline is difficult to realize a circulating function; meanwhile, due to the temperature control automatic circulation system, a user cannot start the system as required, so that a large amount of circulation idle consumption and pipeline heat dissipation idle consumption are generated when the system is idle, and the cost of water saving is changed into a large amount of electric energy consumption. The invention has the advantage that the controllable water return channel can be constructed without laying a special water return pipeline.
